1 Scope
The present document specifies the requirements and technical considerations for Customized Alerting Tone (CAT)
service in both CS and PS domains, especially additional features for roaming and interoperability support.
This document considers voice and multi-media CAT, so the CAT user may experience favourable songs, multi-media
clips or other customized alerting tones.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A
term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].
Alerting Tone: An indication that is played to the calling party during establishment of a call or during an established
call session indicating one of the following:
- that the called subscriber is being alerted.
- the progress of communication request (Call Forward, Call Wait etc.)
- any alerting event during a call session
Customized Alerting Tone: An Alerting Tone that is customized by the called subscriber or the calling subscriber, and
it can contain additional media types.
Customized Alerting Tone Service:A Customized Alerting Tone Service (CAT service) is an operator specific service
by which an operator enables the subscriber to customize his alerting tone.
CAT Inter-action: is the interaction of the CAT service with other services, e.g. CAT Inter-action with Call
Forwarding.
CAT Inter-working : Multiple Domains Inter-working is the interworking of a CAT service over different domains or
subsystems (CS or IMS) as well as between PLMNs.
CAT content provider: A service provider that provides a set of Alerting Tones for use as CAT for subscribers of
the CAT service. A 3GPP operator may be a CAT content provider.

abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in
TR 21.905 [1].
CAT Customized Alerting Tone
4 CAT Service Requirements
4.1 Basic functionality of the CAT service
The Customized Alerting Tone Service (CAT service) is an operator specific service by which an operator enables the
subscriber to customize the alerting tone which is played to the calling party. The calling party does not need to be a
CAT subscriber to experience the CAT set by called subscriber. CAT service should not negatively affect the
conversation between calling and called parties, e.g. no voice/video clipping, no longer communication setup time.
- The service shall support the CAT content types of audio, video, image, graphic, text, location and electronic
business card.
- CAT can contain one or several content types, and at most one element of each type.
- The calling party should be able to simultaneously experience multiple CAT contents, e.g. audio and video.
- The service user shall be able to subscribe the CAT service, activate the CAT service, update the settings, e.g. to
change his active CAT.
- The calling party shall be able to experience the CAT set by the called CAT service subscriber.
- The CAT shall override the default alerting tone towards the calling party.
- The operator should have the capability to store multiple CATs per CAT service subscriber.
- The CAT subscriber should be able to configure the CAT service. The CAT service should be able to select the
appropriate CAT according to the rules. The CAT subscriber profile is based on the following parameters:
1. CAT content descriptor - Pointing to the right content or combination of contents (e.g. personal prompt plus
chosen music track).
2. CAT timing descriptor - Time of day, day of week, specific date and intervals based on each of those
parameters.
3. User (called/calling party) descriptor - user ID (or group ID of users), user presence, user location, CAT user
charging mode
Note 1: As location information may be restricted in some instances, the default user location may be a generic
"unknown".
Note 2: Presence information for a CS user is limited to attached or detached
- The CAT service shall be able to select the appropriate CAT according to the CAT user profile.
- The operator shall be able to verify that the party is authorised to store and update CAT content.
- The operator shall be able to set limitations on file type, file size, etc. for storing the CAT content.
- It should be possible to inform the user about status and changes in his CAT service, e.g. close expiry date for
the CAT service or a particular CAT content.
Note: In the CS domain, this information may be provided by existing means such as SMS and web access.
- The operator shall be able to charge for the CAT service on event, volume or media type basis.

- The called party shall be able to pre-configure the CAT service. The preconfigured service is played upon
receipt of an incoming communication notification. This may be based upon the calling party identity.
- The calling party should be able to reject the CAT service based on rules e.g. time, the identity of the called
party.
- It shall be possible for a CAT subscriber to subscribe to a CAT that is provided by a third party content provider.
4.1.1 CAT functionality in IMS domain
The functions identified here are specific to communications made between users within the IMS.
- The calling party shall be able to experience the CAT set by the calling CAT service subscriber, both when the
calling party is within HPLMN and when roaming.
- The calling party’s operator shall be able to configure which CAT should have priority, the one set by the called
or calling CAT service subscriber. The calling party’s operator shall be able to take into account the calling CAT
service subscriber’s preferences. By default, if no preference is set, the CAT set by the calling party has priority.
- When the called party answers the communication the CAT shall stop or continue to play during the
co
